I have just commissioned a 6mm BRA rifle build and have a few questions regarding reloading equipment. My plan is to fire form by loading 6mm BR with Petersen brass. My question is what dies are needed? My intention is to load just load 6mm BR until I have 250-500 cases fire formed then switch to loading BRA. Will I need to buy a seater in both 6 and 6BRA? I plan to full length size will I need to buy this die in both bullet types? Are there any other concerns to be aware of or thoughts that need to be considered. Any help will be greatly appreciated.

6BRA

6bra sizer and 6bra seater only. If chamber is cut properly, fireform with 105s and 30 gr of varget. Ackleys are supposed.to be cut .004 short, so the case is held in place by a slight crush on shoulder felt on bolt close. Pretty simple. No need to jam.
This!
I use Peterson brass for my 6BRA and it’s been good.
Yep

You can also probably use your 6BR die to size enough of the neck for a 2nd and 3rd firing on a couple of cases (with fireforming load, nothing too hot) and send your 3X fired brass to get a die that best matches your chamber. I started with a Wilson bushing die and found that, compared to my chamber, it sized the body at the shoulder about 0.0005" more than is sized the body at the 0.200 line, creating a more tapered case than the chamber. I sent my brass to Harrell's and then sent me back a die that perfectly matches my chamber, and I can get away with as little as a 0.0005" bump, but usually bump 0.0015 to 0.0020"

Does not work with my reamer and many others.

What size neck?
Out of curiosity what is the problem area?
.200 line?

So I’ve been told… Im using a wheeler print and the alpha gave me some nice smeared ejector marks at about 225 fps slower than my Lapua load. That was years ago. Glad I don’t have to deal with Alpha anymore.
I know you’re not alone with those issues.
I’m not buying an expensive carbide reamer just to run one particular brass brand when my regular reamer works plenty well with other brands.
